Description

Technical Field

[0001] This utility model relates to the field of stainless steel flange technology, specifically to a stainless steel flange that facilitates subsequent disassembly. Background Technology

[0002] Stainless steel flanges are important connecting components in industrial piping systems, mainly used for sealing connections between pipes, valves, and equipment. They are typically made of austenitic stainless steel such as 304 and 316, which have excellent corrosion resistance and mechanical strength. The manufacturing process includes casting, forging, and machining. The surface can be polished or chrome-plated to meet the needs of different working conditions. They are widely used in petroleum, chemical, food, and pharmaceutical fields, becoming an indispensable metal component in fluid transportation systems.

[0003] However, it still has some drawbacks. For example, stainless steel flanges traditionally use bolt fastening for connection. During installation or disassembly, multiple sets of bolts need to be tightened one by one. This is not only cumbersome and time-consuming, but also difficult to meet the special working conditions that require frequent disassembly and assembly, thus reducing equipment maintenance efficiency.

[0004] To address the aforementioned issues, this application proposes a stainless steel flange that facilitates subsequent disassembly. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In this embodiment, as shown... Figures 1-2 As shown, a fixed sleeve 3 is detachably connected to the outer surface of the first stainless steel connecting flange 1 and the second stainless steel connecting flange 2. A rubber sealing ring is provided on the inner wall of the fixed sleeve 3 for tight fit between the flange and the first stainless steel connecting flange 1 and the second stainless steel connecting flange 2 after installation. A threaded cylinder 11 is fixedly connected above the first stainless steel connecting flange 1, and a first connector port 12 is fixedly connected above the threaded cylinder 11. A second connector port 21 is fixedly connected below the second stainless steel connecting flange 2. A hexagonal head 31 is fixedly connected above the fixed sleeve 3. Threaded grooves are opened inside the fixed sleeve 3 and the fixed sleeve 3 is threadedly connected to the outer surface of the threaded cylinder 11.

[0021] In this embodiment, as shown... Figures 3-4As shown, the quick-release hook 4 has an auxiliary disassembly groove 41 on its outer surface, and a hook head groove 51 is provided below the hook fixing groove 5. A hook base 42 is fixedly connected above the quick-release hook 4, and a cylindrical rod is installed above the hook fixing groove 5. The hook base 42 moves inside the hook fixing groove 5 via the cylindrical rod. A fixed hook head 43 is fixedly connected below the quick-release hook 4 and can be detached from the hook head groove 51. Multiple sets of triangular metal strips are provided on the inner side of the quick-release hook 4 and engage with the triangular grooves provided on the inner side of the hook fixing groove 5. When using this device, first align the first stainless steel connecting flange 1 and the second stainless steel connecting flange 2 through the four sets of hook fixing grooves 5, and then rotate the four sets of quick-release hooks 4 to make the hook base 42 rotate along the cylindrical rod, thereby driving the fixed hook head 43. The hook head groove 51 is fully embedded, and the triangular metal strip on the inner side of the quick-release hook 4 engages with the triangular groove of the hook fixing groove 5 to achieve mechanical locking. Then, the fixing sleeve 3 with rubber sealing ring is connected to the threaded cylinder 11 through its threaded groove, so that the fixing sleeve 3 presses the first stainless steel connecting flange 1 and the second stainless steel connecting flange 2 after rotation. The hexagonal head 31 provides a rotation force point. At this time, the first connector port 12 and the second connector port 21 can be connected to the pipeline system respectively. The cavity formed by the fixing sleeve 3 can disperse the stress of the connection part. When disassembling, the hexagonal head 31 is rotated in the opposite direction to lift the fixing sleeve 3. The two flanges can be separated by turning the quick-release hook 4 through the auxiliary disassembly groove 41 to release the fixation. Under the premise of ensuring a certain structural strength, the flanges can be quickly disassembled and assembled.

[0022] Please see Figures 1-4 A stainless steel flange that facilitates subsequent disassembly includes a first stainless steel connecting flange 1 and a second stainless steel connecting flange 2 detachably located below the first stainless steel connecting flange 1. Hook fixing grooves 5 are formed around the outer surfaces of both the first and second stainless steel connecting flanges 1 and 2. Four sets of hook fixing grooves 5 are provided, and quick-release hooks 4 are installed inside the hook fixing grooves 5. The quick-release hooks 4 facilitate rapid connection of the stainless steel flanges, thus facilitating subsequent disassembly. The first and second stainless steel connecting flanges 1 and 2 are quickly connected via hooks. A matching fixing sleeve 3 can cover the first and second stainless steel connecting flanges 1 and 2 after connection, further strengthening the connection and avoiding the cumbersome bolt fixing process.

[0023] Working principle

[0024] A quick-release hook 4 facilitates the subsequent disassembly of stainless steel flanges, enabling rapid connection and subsequent disassembly. The first stainless steel connecting flange 1 and the second stainless steel connecting flange 2 are quickly connected via hooks. A matching fixing sleeve 3 can cover the first and second stainless steel connecting flanges 1 and 2 after connection, further strengthening the connection. This eliminates the need for cumbersome bolt fixing procedures. When using this device, first align the first and second stainless steel connecting flanges 1 and 2 using the four sets of hook fixing slots 5. Then, rotate the four sets of quick-release hooks 4 to rotate the hook base 42 along the cylindrical rod, causing the fixing hook head 43 to fully engage with the hook head slot 51. Simultaneously, the triangular metal strip on the inner side of the quick-release hook 4 engages with the triangular groove of the hook fixing groove 5 to achieve mechanical locking. Then, the fixing sleeve 3 with rubber sealing ring is connected to the threaded cylinder 11 through its threaded groove, so that the fixing sleeve 3 presses the first stainless steel connecting flange 1 and the second stainless steel connecting flange 2 after rotation. The hexagonal head 31 provides a rotation force point. At this time, the first connector port 12 and the second connector port 21 can be connected to the pipeline system respectively. The cavity formed by the fixing sleeve 3 can disperse the stress of the connection part. When disassembling, the hexagonal head 31 is rotated in the opposite direction to lift the fixing sleeve 3. The two flanges can be separated by moving the quick-release hook 4 through the auxiliary disassembly groove 41 to release the fixation. Under the premise of ensuring a certain structural strength, the flanges can be quickly disassembled and assembled.
